Title
(EN) A COMPOSITION FOR LACQUERING GLASS SUBSTRATES
(FR) COMPOSITION DE LAQUAGE DE SUBSTRATS EN VERRE
Abstract
(EN)
A composition for lacquering glass substrates is provided. The composition of lacquering comprises of about 10–90% of a resin, about 2–40 % of filler selected from the group consisting of inorganic particles, about 2–50% of pigments selected from the group consisting of metal pigments or color pigments, about 1–30% of cross linkers selected from an amine group or an epoxy group or an acrylic group, about 0.1–10% of adhesion promoters and about 0.1–5% of surfactants dissolved in about 1–60% of water. The composition for lacquering glass substrates is devoid of any organic solvents. The present disclosure further relates to a method of making a lacquered glass article using the lacquer composition. The lacquered glass article prepared according to the present disclosure has a gloss value ranging between 10–100 R-60 ͦ.

L'invention concerne une composition de laquage de substrats en verre. La composition de laquage comprend environ 10 à 90 % d'une résine, environ 2 à 40 % d'une charge choisie dans le groupe constitué de particules inorganiques, environ 2 à 50 % de pigments choisis dans le groupe constitué de pigments métalliques ou de pigments colorés, environ 1 à 30 % de réticulants choisis parmi un groupe amine ou un groupe époxy ou un groupe acrylique, environ 0,1 à 10 % de promoteurs d'adhérence et environ 0,1 à 5 % de tensioactifs dissous dans environ 1 à 60 % d'eau. La composition de laquage de substrats en verre est exempte de solvants organiques quelconques. La présente invention porte en outre sur un procédé de production d'un article en verre laqué à l'aide de la composition de laquage. L'article en verre laqué préparé selon la présente invention possède une valeur de brillance comprise entre 10 et 100 R-60 ͦ.
